Shenzhen Topmay Electronic Co., Ltd is specialized in manufacturing a wide range of capacitors and resistors.
The company headquarter is located in Shenzhen, a flourishing southern city that is recognized as one of the economic centers of China. Since established in 1998, Topmay deal globally based on the most competitive price and excellent service. Through many years’ hard work, it has gradually grown up to be an outstanding enterprise in the field of capacitors and resistors.
By closely following the latest market trends, we provide “one-stop” capacitors and resistors solution, which are applied in almost all kinds of PCB, communications, lighting, home appliance, industrial control, green energy, etc.
All the time, Topmay holds an idea that the products quality is the life of a company. We have passed ISO9001 quality system authentication and process strong research and development center and experienced service team. In order to serve our customers better, we have made investments so that our products can meet quality standards of UL, CE, SGS, CQC, etc.
With these advantages, we have good reputation among global customers.
Topmay thanks for all trusts and supports from every customer. We are willing to cooperate with domestic and foreign customers to meet prosperity together, generations by generations.

FAQ Of Topmay Capacitor
1) Can I have a free sample to test ?
Yes, we could provide free samples to test and check quality.
Freight cost is collected.
2) What is the lead time?
Sample needs about 7~10 working days prepared; mass production
average time takes 15-20 working days
3) Do you have any MOQ limit?
Yes. But it depends on product. Normally MOQ is 2K~10Kpcs
4) How about price terms?
We do FOBSHENZHEN if order amount is more than 5000USD. Less than
that, it is EXWSHENZHEN and we do not undertake local charge.
5) What information should I let you know if I want to get a
quotation?
Basically for capacitor, it requires to know detailed capacitance
and voltage. If you have more information, such as type, product
photo for reference, you could kindly provide too.
